Abstract

A filter cartridge (12) that has a first and second layer of filter media (38, 40) that each have first and second major surfaces (32, 44) and a perimeter (46) and that each contain active particulate that is bonded together. A plenum (42) is disposed between the first and second layers of filter media (38, 40) such that the plenum (42) interfaces with the second major surface (44, 44') of each layer of filter media. A housing sidewall (30) extends from the first layer of filter media (38) to the second layer of filter media (40) and is secured to the perimeter (46) of the first and second layers of filter media. The first major surfaces (32, 32') of the first and second layers of filter media (38, 40) are each fluid permeable and are each in fluid communication with an exterior gas space. A filter cartridge (12) having such a construction provides a bifurcated flow pattern in a higher volume structure.
